HEADER FOR A HEAT EXCHANGER

摘要

A heat exchanger collector comprising a plurality of connecting tubes, where sets of connecting tubes arranged side by side in a plane are superimposed in layers one on the other for an interlocked connection with mating profile elements inserted in the tube end area. In order to produce a closed wall of the collector, the connecting areas between the tube ends and the mated elements are joined together by, e.g., brazing to prevent the ingress of fluids. The sealed joint to exclude liquids can be achieved also successively in the layer-by-layer construction. The profile elements have recesses for the tubes and further blind recesses for flexibility and thermal effects.
